Title: Lens molds with protective coatings for production of contact lenses and other ophthalmic products
Inventor: LI HONGWEN
IPC: B29C33/38
Filed: 2000-06-08
Abstract: This invention relates to the preparation of molds (10) for the production of contact lenses and other ophthalmic articles. By using an inorganic material to coat the optical surfaces (2, 3) and sidewalls (12, 13) of mold parts (6, 7) made from clear-resin materials, manufacturers can produce lens molds (10) with greater dimensional stability and chemical resistance. In addition to protecting the clear resin from interaction with otherwise reactive monomers from which the molded article (8) is made, such coatings (11) can also be used to achieve preferential release of the molded article. The resulting mold (10) is especially useful for providing an economical way to improve manufacturing quality of contact lenses.

Inventor: OKAMOTO HIROSHI
IPC: A61P3/10
Filed: 2001-06-01
Abstract: It is indicated that the expression of Reg gene in .szlig. cells can be remarkably induced and thus the proliferation of .szlig. cells can be promoted by using an inflammation transmitter IL-6 together with glucocorticoid. It is also indicated that HGF inhibits apoptosis induced by Reg protein and that IL-6 and glucocorticoid induce the expression of HGF gene in cells. PARP  inhibitors such as nicotinic acid amide and 3-aminobenzamide further enhance the induction of the expression of these genes. Moreover, the expression induction mechanism is analyzed by using the promoter regions of Reg gene and HGF gene and a method of efficiently screening candidate compounds for these gene expression inducers is developed.

Abstract: A method of characterizing the biophysical properties of G protein-coupled receptors in response to binding by ligands. The clone human .delta.opioid receptor immobilized in a solid-supported lipid bilayer was investigated by a method featuring coupled plasmon-waveguide resonance (CPWR) spectroscopy. Th e invention offers a highly sensitive method that directly monitors mass density, conformation, and molecular orientation changes occurring in anisotropic thin films, and allows direct determination of binding constants . Although both agonist and antagonist binding to the receptor cause increases  in molecular ordering within the proteolipid membrane, only agonist binding induces an increase in thickness and molecular packing density of the membra ne (10). This provides a method of discriminating between agonist and antagonis t binding.
